Application filed August 17, 1900. $erial No. 27,125. (No model.)

To all whom 1125 may concern:

Be it known that I, ADEMOR N. PETIT, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented an Improvement in MachinesforDuplicating Phonograph or SimilarRecords, of which the following is a specification.

My present invention is designed as an im- [0 provement upon the devicesshown and described in. my prior Letters Patent, one dated September 11,1900, No. 657,785, and the other dated November 20, 1900, No. 662,301.

The present invention is designed to improve the structure andefficiency of the devices of the former applications, to bring thestyles more closely down to their work upon the record and blankcylinders, to permit a latitude of movement to the following style,

and to make more positive the movement of the duplicating-style.

In carrying out my present invention I employ a detachable back shaft,which may be removed from the bed and with it the following andduplicating styles and the devices carrying the same, and I also employan improved form of coupler for the axial shafts, centering the same andcausing them to travel in unison, and a swing-arm bracket, lockingbolt,and spring locking device, the bracket carrying the shaft of the sleeveor mandrel for supporting the blank cylinder and said devices couplingthe same to the main shaft and locking the same in position. In connec-5 tion with the shaft for the mandrel of the blank cylinder I employfriction devices for holdingthe mandrel upon the shaft, but which permitof the ready removal of the mandrel, if desired. A lifting-bar isemployed for rais- 0 ing the arms, the devices connected thereto, andthe styles carried thereby to elevate the styles above the record andblank cylinders, and I further employ peculiar devices connected to thefollowing and duplicating styles 5 and by which their operation isefiected, said devices being connected together so as to operate inunison, the devices of the following style being supported so that alatitude of movement is permitted the following style in followinguneven grooves upon the recordcylinder, and the devices carrying theduplicating-style are so connected that only an upand-down movement ispermitted, insuring a more perfect duplication of the record. Thedevices of my present invention are also applicable to the duplicationof sound-records from a master-roll.

In the drawings, Figure 1 is a plan representing my improvement. Fig. 2is an inverted plan of the following and duplicating styles and devicesconnected therewith. Fig. 3 is an end view of the parts shown in Fig. 1from the right hand. Fig. 4c is a cross-section and partial elevation atabout the line new of Fig. 1. Fig. 5 is a partial plan and section atthe connection between the shaft of the record-cylinder and the shaft ofthe blank cylinder. Fig. 6 is an end view of the coupling device forconnecting the axial shafts. Fig. 7 is a partial elevation and sectionof the spring locking device for connecting the pivoted arm carrying theshaft of the blank cylinder and mandrel to the frame of the Ina-- chine.Fig. Sis a sectional plan of the shaft, mandrel, and blank cylinder,togetherwith the frictional engaging devices for connecting the same.Fig. 9 is an elevation showing the application of my improvement to theproduction of a record on an ordinary blank cylinder from a master-rollof exaggerated size. Fig. 10 is an end view of the master-rolland the blank cylinder, together with the styles coming in contact withthe surfaces thereof. Fig. 11 is an end elevation of theduplicatingstyle device shown in Fig. 9. Fig. 12 is an inverted plan,and Fig. 13 a side elevation, in larger size, of a modified form ofdevices carrying the duplicating-style. Fig. 14 is an elevation inlarger size of the duplicating-style shown in Figs. 2 and 3.

The shaft a is mounted in and supported by suitable bearings upon thebed. A part of said shaft is exteriorly threaded and provided with apulley for its rotation, and the fixed sleeve or mandrel b is secured atone end of said shaft and carries the record-cylinder d.

0 represents the removable sleeve or mandrel, and e the blank cylinderthereon. The back rod f is supported upon the bed of the machine bystandards, in which are the removable pin centers 5, held in place byscrews 6, which provide for the removal of the rod and the parts carriedthereby. The sleeve 9 surrounds the rodf, and a sleeve h is carried bythe sleeve g, and a curved arm 11 is made integral with the sleeve h andextends forward over the record-cylinder d, and a screw-feed 2 isconnected to the sleeve g with a half-nut made in the usual formengaging the threaded portion of the shaft a and by which the sleeve 9is moved lengthwise of the rod)".

The curved arm '0' terminates in a rest-bar 70, formed as an integralcontinuation of the said arm, and this arm i supports an arm Z, securedthereto and at right angles to the arm 1' and parallel with the shaft a.The bed of the machine is provided with a rest and guide 3 for therest-bar k, the same being substantially a straight edge upon which thebar rests and along which it moves with the movement of the sleeve 9, soas to maintain the styles in a fixed relation to the cylinders. Iprovide a pivoted frame 4, having a finger adapted to be engaged by thehand, the said frame acting when swung and its outer end elevated tocome against the restbar It and raise the same, together with the curvedarm 2', the arm Z, and the devices carrying the styles, to move the sameaway from contact with the record and blank cylinders.

The arm m is pivoted at 7 to the bed of the machine and the shaft 7'passes through a hub made integral with or connected to the said arm m.This shaft r is preferably reduced at its free end and surrounded by asleeve 13, removably fixed thereto by ascrew, and a spring 14 in arecess in the said sleeve is also secured by a-screw, (see Fig. 8,) andthe removable sleeve or mandrel c is preferably constructed with aninternal sleeve 15, secured thereto, the sleeve 15 being preferably ofmetal and screwed to the mandrel 0, while the mandrel 0 may not be ofmetal, but is tapering and adapted to receive the blank cylinder e.WVith this construction the mandrel c and sleeve 15 may be readily andquickly removed from the shaft 0 and the sleeve 13, if desired, or thisconstruction will facilitate taking the cylinder 6, after theduplication of a record, away from the taper mandrel c, the shaftr,sleeve 13, and spring 14 constituting the friction device for holdingthe taper mandrel c in place upon the shaft during the duplication ofthe record.

The hub 16 is at the exposed end of the shaft 1", and it is made with apointed center and with a circular row of holes around the pointedcenter, and the free end of the shaft a has a recessed center and aprojecting pin 17, and in coupling the shaft a to the shaftr therecessed end of .the shaft a receives the pointed center of the shaft 1'and the pin 17 enters one of the holes of the row of holes in the hub16, and these holes come closely to gether, so as to receive the pin 17at almost any position of the blank cylinder when the same is upon thetaper mandrel 0, so that no special adjustment is necessary.

I provide jaws 12 on the stationary bed of the machine, and a handle 9is pivoted to said jaws by the pin 10, and I provide on the pivoted armm a spring-frame 11. This springframe 11 is especially shown in Figs. 1,3, and" by screws to the pivoted arm m and a central V portion bentoutward and over backward and A standing slightly away from the fixedpart 7 i 7 and comprises end portions that are-secured tion by thehandle 9 and spring-frame 11.

The arm Z carries the following and duplicating styles and the partsacting in connection, as follows: The bracket 3, inclined, as shown inFig. 4:, is provided with an opening for the arm Z, and a set-screwsecures the said bracket 3 to said arm, and at the free end of the arm Zthere is a yoke-bracket t, also secured to the arm by a set-screw. Aplate u, having a tongue passing into a recess or mortise in the bracket3, is pivotally connected to the said bracket by a pin passing throughthe tongue, and there is preferably a looseness at this pivotalconnection, so that the plate.

u not only has an up-and-down motion, but a lateral motion to a certainextent, and a screwrod and weight 18 are preferably connected to thelower or free end of the plate at. The following style 12 is upon a barpivoted to the frame u, and a link 19, passing through an opening in theplate to, connects the bar of the followingstyle with a spreadbell-crank lever 20, pivoted in bearings to the bracket 8,

the position of the bell-crank lever 20 being.

fixed and that of the following style n being movable upon the plate a.The said lever 20 consequently rocks with the movement of the followingstyle. At the lower edge and in the under surface of the plate a Iprefer to make a pointed recess and to employa hook 21, the point ofwhich passes into the recess and the stem of which passes below the saidplate and r is secured to the bracket 8, the office of this hook beingto limit the movement of the plate utoward the record-cylinder and holdthe plate when the parts are elevated by the pivoted frame 4, it beingpossible between the Weight 18 and the movement of'the followingstyle,its arm, the link 19, and the spread bell-crank lever 20 to effect adelicate adj ustment that will cause the following style 92 to transmit,through the rod 8, to the du-' plicating-style the movements caused bythe delicate undulations of the record-cylinder. The head 0 is pivotallyconnected to the yokebracket 2, and this yoke-bracket is provided withbearings for the rod 22, said rod 22 in. i

turn being provided with an arm carrying the 8s" axial shafts the saidparts are held in posi- I duplicating-style 0, and a second arm to whichthe spring 23 is connected at one end, with the other end of the springconnected to an adjustable tension-screw 25. The rod 22 occupies aposition at right angles to the axial line of the shafts a and 1*, whilethe arm connected thereto and carrying the duplicatingstyle 0 is atright angles-to the rod 22 and axially in line with the said shafts, andsaid rod 22 carries arms to which are pivoted the connecting-rod 8, saidrod 8 extending across between the bell-crank lever 20 of therecordingstyle and the rod 22 of the duplicating-style, the said rodforming a fixed connection between the respective styles efiecting thesimultaneous movement of the styles, or, in other words, causing therespective styles to operate in unison and the duplicating-style torepeat the delicate movements of the following style. I provide a pin24, passing through the yoke-bracket and into a recess in the pivotedhead r, so as to limit the movement of the head '0 and prevent the samedropping when the arm Z and parts connected thereto are swung upward.

In connection with the duplicating-style I also employ a guide 26,connected to the pivoted head t, and preferably vertically adjustable,the office of which is to rest upon the surface of the blank cylinder 2and following the contour of the surface thereof to give location to theduplicatingstyle o, effecting a proper regular movement of theduplicatingstyle and insuring the proper depth of out.

In Figs. 9, 10, and 11 I have shown a modified construction of myimprovement in which the following and duplicating styles and thedevices supporting the same are adapted for use with the master-roll 10,upon which has been made a sound-record, the said sound-record beingreally of magnified size or proportion on account of the exaggeratedsize of the master-roll, the surface thereof in making the record havingtraveled faster than would be the case with the regular size ofcylinder. In this modification the devices of the following style arepractically identical with those shown in Figs. 2 and 4t, and thedevices of the duplicating-style are almost the same as those shown inFigs. 2 and 3, there being, however, a slight modification in theconstruction, so as to transmit the movement of the connecting-rod 8down to the duplicating-style 0, said device generally comprising a rod27 and an arm 28 connected thereto, and which arm carries theduplicating-style. In this modification the parts are so proportionedthat the cuttings in the cylinder e, duplicating the sound-record, willbe properly rendered. In this device the eye secured to the head 1',Figs. 9 and 11, and the pin 30, connected to the yoke-bracket t, performthe same function as the pin 24E-viz., that ofpreventing the head ofalling when the parts are elevated.

In the form of dnplicating-style shown in Figs. 12 and 13 the armcarrying the style projects from the opposite side of the rod 22 fromthat shown in Figs. 2 and 3 and the u spring 23 is dispensed with. Theduplicatingand its downward movement being influenced by the adjustableweight 18, the tension-spring is not required and the movement is madepositive.
